福州市大气汞含量及变化特征分析

Analysis on atmospheric mercury contents and their variation characteristics in Fuzhou city,Fujian Province

在福州市采集了10个点位共356件大气样品,测试结果表明,福州市大气汞含量35.82~586.11 ng/m3,各点平均值89.86~168.24 ng/m3,总平均111.9 ng/m3,大气汞含量空间变化特征表明高含量点与地热活动带在空间上相吻合。

356 atmospheric mercury s^mples were collected at 10 sampling locations in Fuzhou city, Fujian Province. The analysis result shows that the atmospheric mercury contents in Fuzhou city are 35.82-586. 11 ng/m3,the average values from the different sampling locations are 89.86-168.24 ng/m3, the total average value of the 356 samples is 111.9 ng/ mL The spatial variation characteristics of the atmospheric mercury contents show that the high content locations are spatially coincided with the geothermal activity zones.
